     talk - talk to another user

     talk address [terminal]

     The talk utility is a two-way, screen-oriented communication

     When first invoked, talk sends a message similar to:

     Message from TalkDaemon@ her_machine at time ...
     talk: connection requested by your_address
     talk: respond with: talk your_address

     to the specified address. At this point,  the  recipient  of
     the message can reply by typing:

     talk your_address

     Once communication is established, the two parties can  type
     simultaneously,  with  their  output  displayed  in separate
     regions of the screen. Characters are processed as follows:

       o  Typing the alert character will alert  the  recipient's

       o  Typing Control-L will cause the sender's screen regions
          to be refreshed.

       o  Typing the erase and kill characters  will  affect  the
          sender's  terminal  in  the  manner  described  by  the
          termios(3C) interface.

       o  Typing the interrupt or  end-of-file  (EOF)  characters
          will  terminate  the  local talk utility. Once the talk
          session has been terminated on one side, the other side
          of the talk session will be notified that the talk ses-
          sion has been terminated and will be able to do nothing
          except exit.

       o  Typing characters from LC_CTYPE  classifications  print
          or  space will cause those characters to be sent to the
          recipient's terminal.

       o  When and only  when  the  stty  iexten  local  mode  is
          enabled,  additional  special  control  characters  and
          multi-byte or single-byte characters are  processed  as
          printable    characters   if   their   wide   character
          equivalents are printable.

       o  Typing other non-printable characters will  cause  them
          to  be  written to the recipient's terminal as follows:
          control characters will appear as a caret (^)  followed
          by the appropriate ASCII character, and characters with
          the high-order bit set will appear in "meta"  notation.
          For  example, `\003' is displayed as `^C' and `\372' as

     Permission to be a recipient of a talk message can be denied
     or  granted by use of the mesg(1) utility. However, a user's
     privilege may further constrain the domain of  accessibility
     of  other users' terminals. Certain commands, such as pr(1),
     disallow messages in  order  to  prevent  interference  with
     their  output.  talk  will  fail  when  the  user  lacks the
     appropriate privileges to perform the requested action.

     Certain block-mode terminals do not have all  the  capabili-
     ties  necessary to support the simultaneous exchange of mes-
     sages required for talk. When this type of  exchange  cannot
     be  supported on such terminals, the implementation may sup-
     port  an  exchange  with  reduced  levels  of   simultaneous
     interaction  or  it  may  report  an  error  describing  the
     terminal-related deficiency.

     The following operands are supported:

     address         The recipient of the talk session. One  form
                     of  address  is the username, as returned by
                     the who(1) utility. If you wish to  talk  to
                     someone  on  your own machine, then username
                     is just the person's  login  name.   If  you
                     wish to talk to a user on another host, then
                     username is one of the following forms:


                     although user@host is perhaps preferred.

     terminal        If the recipient  is  logged  in  more  than
                     once,  terminal  can be used to indicate the
                     appropriate terminal name.  If  terminal  is
                     not  specified,  the  talk  message  will be
                     displayed on one or more  accessible  termi-
                     nals  in use by the recipient. The format of
                     terminal will be the same as  that  returned
                     by  who.

     See environ(5) for descriptions of the following environment
     variables  that  affect the execution of talk: LANG, LC_ALL,

     TERM            Determine the name of the invoker's terminal
                     type.  If this variable is unset or null, an
                     unspecified terminal type will be used.

     The following exit values are returned:

     0        Successful completion.

     >0       An error occurred, or talk was invoked on a  termi-
              nal incapable of supporting it.

     Typing Control-L redraws the screen, while the erase,  kill,
     and  word  kill  characters  will work in talk as normal. To
     exit, type an interrupt character. talk then moves the  cur-
     sor to the bottom of the screen and restores the terminal to
     its previous state.
